ROLLER FOR SLIDING DOORS.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed August 10, 1910. Serial No. 576,487.

To all whom it may concern:

Be it known that I, NICKOLAS KLoTz, a citizen of the United States of America, residing at Niagara, in the county of Grand Forks and State of North Dakota, have invented new and useful Improvements in Rollers for Sliding Doors, of wh ich the following is a specification.

This invention elates to stay rollers for sliding doors and particularly to a roller.

which is designed to engage the lower portion of the door so as to hold the door in close contact with the casing; the object of the invention being to employ a novel and effective bracket for yieldingly and slidably supporting the roller.

I n the drawing, forming a portion of this specification and in which like numerals of reference indicate similar parts in the sev eral views :F igure 1 is a perspective view of my improved roller. Fig. 2 is a detail vertical section through a portion of a sliding door showing the application of the roller thereto. Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 2.

The invention is designed particularly for use in connection with sliding barn doors or the like, and it consists of a bracket 1 which is formed to provide a vertical apertured flange Q i'hich is attached to the sill or casing portion 3 of the barn or inclosure by From the flange 2 the bracket exand then upwardly in parallel relationto the part 2 and then outwardly to form a horizontal base 6. The base (S has its outer extremity extended upwardly, as shown at 7, and then for\vardly,as shown at 8, the said portion 8 being disposed immediately above the base 6; The side edges of the portion 8' are formed to provide depending guide flanges t) and the side edges of the base 6 u'e"lormed to provide upstanding guide flanges 10.

The portion 7 of the bracket is formed to provide a passage 11: through which the stem 1201: the sliding roller support 13'extends. The sliding roller support moves on the base 6, and as illustrated, such support consists of a substantially Ushapedmember whose arms 14 are formed to provide bearings. 15 in which the ends of the axle 16 of the roller 17 are mounted. The axle 16 is provided with a lower washer 18 and an upper washer 19. These washers are designed to engage the arms 14 of the support 13 to prevent the roller 17 from contacting therewith. It may be stated that the opening 11 is somewhat larger than the diameter of the stem 12 and that the support 13 is mounted on the bracket 1 for slight lateral movements to allow for any sudden thrust thereof in one direction 'or the other'against the roller. The flanges 10 while being designed to guide the support 13 in its movement also serve to prevent the strain from being applied entirely to the axle of the roller and to the stem 12. To hold the roller I? normally in an extended position to cause the same to bear against the door to hold the door sccurely closed against the inclosure, I provide a relatively strong spring 20 which is coiled around the stem 12 and confined be tween the support 13 and the washer 21, as clearly'shown in Fig. 2 of the drawing. The washer 21 is located on the inner side of the upstanding part 7 of the bracket and as illustrate, the washer 22 bears against the outerside of the upstanding part 7. The lastnamed washer is adapted to be engaged by the removable cotter pin 23. The pin extends through an aperture near t -he=outer extremity of the stem 12, its oiiice being to limit the movement of the support-11in one direction.

The device when mounted as hereinbefore described will accommodate any irregularities of the surface of the door and will obviate the door becoming bound should extending from the support and having its opposite end extending through the said around the stem and confined opening to permit horizontal lateral movement of the support on the bracket, guide flanges formed an the bracket for engaging the support t0 limit the horizontal sliding movement thereof, and a sprin extending tween the bracket and s11 port respectively to hold the support norme 1y extended on the bracket.

In testimony whereof I afiix my signature in presence of two witnesses.
